HOLDER FOR SHADES OR REFLECTORS.

i Application led .October 4, 1922. Serial No. 592,417.

My invention relatesto holders for shades and reflectors. The object ofmy invention is to provide an efficient holder which can be veryconveniently mounted and operated to release or clamp the reflector orshade without injury thereto.

According to my invention, I provide an inner member which preferablycomprises a plurality of prongs which arehook-shaped at the bottom toengage the lip at the top of the shade or reflector and are sufficientlyresilient to permit spreading to insert the lip of a reflector. A casingis providedhaving at its bottom a shoulder against which the top surfaceofthe reflector or shade bears.

Means are provided for relatively moving the hooked prongs and thecasing so asto clamp the lip of the shade or reflector between the hooksand the shoulder on the outer casing. The casing serves, not only toprovide 'theaforesaid shoulder, but also to confine the prongs, toprevent the spreading of the same, and to `maintain their hooked ends infirm engagement with the lip of the shade or reflector without exertinglateral pressure. The casing is preferably arranged so that it does notrot-ate during the clamping operation. In this manner, the clamping1force may be exerted in an axial direction on v.

In the drawing I have shown one form of my invention. Fig. 1 is anelevation thereof; Fig. 2 is a vertical section; Fig. 3 is a top planview; Fig. 4 is a plan view with the casing cover removed; and Fig. 5 isa side elevation of one of the prongs. i 1

. Referring to the drawing, the usual porcelain socket 10 is providedfor the reception of an incandescent lamp; The insulating upper portion11 thereof is attached to a stud 12, the upper `ends of prongs 13 beingclamped between these parts. The stud may be used inifixedly supportingthe lighting unit. This stud is threaded on theoutside to cooperate withthe casing referred to; These prongs are preferably made of steel orother resilient material "and have shade engaging hooks 14 atthe freeends thereof. These prongs may be comparatively rigid as it is onlynecessary to spread them slightly to pass in the lip or bead of thereflector. The upperportion 15 of the reflector or shade is supported by`the holder, the upper lip 16 thereof being engaged by the hooked prongends 14, these f hooks being so shaped that they pass in underneaththelip or bead, and to engage i the lower surface thereof. A casing orcover is` provided which preferablyconsists of two members 17 and 18.The former is provided .with inner shoulders,`or abutments 19, which areengaged b the upper surface 20 of the reflector or sha e. The uppercasing member or cap 18 has a heel extension `21 which is screw threadedinternally to engage external threads on the stud 12. 1

In use, the cap 18 having been unscrewed, the lip of the reflector orshade is forced into .engagement `with theprong hooks. To facilitateplacing the reflector in the shade engaging hooks 14, the inner wall ofthe casing 17 is flared outwardly at its lower end as 1ndicated. The cap18 is then screwed down upon thestud 12, forcing the lower member 17downwardly toward the prongs 13, thus causing the clamping of the lip 16between `the hooks 14 and the shoulder 19. The casing member 17 bearsagainstand keeps the hooks in close engagement `withthe lip 16, Whilethe prongs prevent rotationl of the casing member about the socket. Itprevents the spreading of the hooks without causing any wedging actionwhich would tend to compressthe reflector.` The result is that thereflector or shade is held very securely and, at the same time, onaccount of the comparatively large bearing surface, the dangerofbreakage or injury isdiminished.` Toremove the reflector or shade fromthe holder, the member or cap 18 is unscrewed and the casing member maybe raised so that the shoulders 19, are drawn away from the 11pper endof the reflector and the lower end of y the casing member 17 having thelarger di` ameter brought opposite the hooks which may now be spread torelease the reflector. It will thus be noted that the pressure isapplied in an axial direction only, without any tendency to squeeze orcollapsethe bead of the reflector. Also that on account ofthe extendedsurface, one is able to clamp the reflector in placeby means of twoprongs placed on opposite sides of the socket. To prevent the casingmember from falling off they hooks 14, the lower` ends of the hooks aremadewider, as indicated in Figure` 5 so as to engage the ends of theshoulders or abutments 19. i

`What I claim as new and desire to secure by Letters Patent of theUnited States is:

1. A holder `for shades or reflectors com-` prisingmembers having hookedends to engage underneath the lip of said shade or re- Hector, a casingextending about said mem-- bers and having an inner shoulder engagingthe top surface of said shade or reflector., and means whereby saidhooked ends and said shoulder may be drawn together along the aXis oi'the casing to clamp said lip or separated to release the same.

2. In a shade holder, a casing having an interiorly disposed interruptedflange consisting of a plurality of spaced flange sec tions, a socketmember mounted in said casingfor axial movement relative thereto, hookarms carried by the socket member andengaging in the spaces between theflange sections, andmeans to move the socket member axially withrelation to the casing whereby a shad'elip engaged by the hook arms willbe forced against the :tlange sections.

3. In a shade holder, a. casing having an interiorly disposedinterrupted flange con sisting of a plurality of spaced lange msections, a Socket member mounted in said casing foraxial movement relativethereto, hook arms carried by the socket member and engaging in thespaces between the iiange sections, a screw threaded stud on the upperend ofsaidsocket member, and a cap threaded on the stud and engaging theupper end of the casing to move the socket axially of the casing uponrotation of said cap whereby a shade lip engaged by the hook armswill beforced against the flange sections..

4. In a shade holder, a socket, a pair of members nonerota-t-ablysupported at the rear end of the socket and carried alongside thesocket, the free ends ofsaid members having shade engaging hooks, athreaded member carriedtbythe socket, and a two part casing, one partbeing threaded to the threaded member, the other part being providedwith interiorly disposedabutments positioned to engage the upper end ofa shade. said hooks passing between the abutments to prevent relativerotation of thesocket and said other part of the casing, the hooksengaging the lip of the shade and holding it in place as pressure isapplied to the upper end o'f the shade by relatively turning thethreaded parts to move thel abutments axially of the socket towardtheshade.

5. In a shade holder, a socket, a pairo'f members non-rotatablysupported at the rear end ofthe socket and carried alongside the socket,the free ends of said members having shade engaging hooks, a threadedmember carried by the socket, and a two part casing, one part beingthreaded into the threaded member, the other part being` provided withinteriorly disposed abutments positioned to engage the upper end of ashade. said .hooks engaging the lip of the shade and holding it in placeas pressure is applied to the upper end ofthe shade by relativelyturning the threaded partsto move the abutments axially oi` the sockettowards the shade, theconiig uration of the casing being such that thehooks may be spread to. release the. shade only when the threaded parts`are turned to permit moving the abutments away from the shade.

6. In a shade holder, a socket, a pair ot' members non-rotatablysupported at the rear end oi the socket and carried alongside thesocket, the free ends of said members having shade engaging hooks, athreaded member carried by the socket, and a two part casini?, one partbeing threaded to the threaded member, the other part being providedwithinteriorly disposed abutments positioned to engage the upper `end ofa shade, said hooks engaging the lip of the shade and holding it inplace as pressure is applied to the upper end of the shade by relativelyturning the threaded parts to movethe abutments axially of the sockettoward the shade, said hooks having laterally extending shouldersengageable with withthe abutments to `prevent `removal ol said othercasing part over the hooks.

7. A holder for shades or the like provided with a peripheral lipadjacent theupper end comprising, hook-shaped members relativelyimmovableinthe direction lof1 the axis of the shade and engageableunderneath the lip, a movable casing having shoulders engageable withthe upper end of the shade, and screw threaded means for forcing theshoulderslin the direction of the axis ofi the shade toward the endofrthe shade lip.

8. In a shade holder, in combination, a lamp socket, a pair of membersixedly carried by the socket structure, each member having a shadeengaging hook, a casingfcarried out side the members and slidabletherealong, said casing being provided with inwardly di rected abutmentsbetween the members, screw threaded meansi'or forcing the abutments inthe directionof` the axis of the shade toward the end of the shade, andcooperative screw threaded means for sliding the casing along themembers andl forcing, the abutments against the upper end of the shadewhose lip is engaged in the hooks.

9. In a shade holder, in combination, a lamp socket, a casing outsidethe lamp socket, socket carried means cooperative with the casing fornon-rotatably guiding it` for reciprocation along the socket, screwthreaded devices for .effecting said movement, shade engaging means inthe form of hooks iixedly carried by the socket and shoulders inside thecasing, so arranged as to exert clamping force in an axial directiononly.

10. In a combined shade holder and lamp socket for use with ashadehaving a lip for engagement by the shade holder, a threaded stud atthe upper end of? the lamp socket, hook members attached to the stud andextending downwardly, a casing! outside the hooked members and havinginteriorly disposed pes ripheral flanges, the ends of which are spacedapart and between which the hook members pass to prevent relativerotation of the casing and hook members, the hook members beingengageable underneath the lip of the shade, and an upper cover memberthreaded on the stud and bearing on the Casing to draw the hook membersupwardly and cause the flanges to press against the top of the shadeforclamping the shade between the flanges and the hook members.

1l. In a shade holder, in combination, a lamp socket, a casing outsidethe lamp socket, straps flxedly connected at their upper ends to thesocket and extending downwardly along the socket, casing carried meanscooperative with the straps for nonrotatably guiding the casing forreciprocation along the socket, the lower ends oit' the straps beingshaped to enga-ge underneath the lip of a shade, the lower end of thecasing being provided with means to engage the upper end of the shadeand with means to confine the lower ends of the straps to prevent radialmovement thereof when axial pressure is applied to clamp the shade inplace, a screw threaded device also carried by the upper end of thesocket, and a threaded member cooperative therewith and with the upperend ot' the casing for axially moving the casing against the shade.

In witness whereof, I have hereunto set my hand this 29th day ofSeptember, 1922.
